A quarter of humanity faces looming water crises

A quarter of humanity faces looming water crises

The New York Times reports: Countries that are home to one-fourth of Earth’s population face an increasingly urgent risk: The prospect of running out of water. From India to Iran to Botswana, 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have, according to new World Resources Institute data published Tuesday. Many are arid countries to begin with; some are squandering what water they have. Several are relying…

We must change food production to save the world, says leaked report

We must change food production to save the world, says leaked report

The Guardian reports: Attempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week. A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless there is also a transformation in the way the world…

‘Nature is declining at rates unprecedented in human history,’ says director of biodiversity conservation group

‘Nature is declining at rates unprecedented in human history,’ says director of biodiversity conservation group

The Guardian reports: From the tops of trees to the depths of the oceans, humanity’s destruction of wildlife is continuing to drive many species towards extinction, with the latest “red list” showing a third of all species assessed are threatened. The razing of habitat and hunting for bushmeat has now driven seven primates into decline, while overfishing has pushed two families of extraordinary rays to the brink. Pollution, dams and over-abstraction of freshwater are responsible for serious declines in river…

The terrifying sound of a human voice

The terrifying sound of a human voice

Ed Yong writes: In the summer of 2017, the mountain lions, bobcats, and other residents of the Santa Cruz Mountains were treated to the dulcet tones of the ecologist Justin Suraci and his friends, reading poetry. Some of the animals became jittery. Others stopped eating. A few fled in fear. Suraci, who’s based at the University of California at Santa Cruz, wasn’t there to see their reactions. He and his colleagues had strung up a set of speakers that would…

Research on honeybees hit by Trump budget cuts

Research on honeybees hit by Trump budget cuts

CNN reports: The US Department of Agriculture has suspended data collection for its annual Honey Bee Colonies report, citing cost cuts — a move that robs researchers and the honeybee industry of a critical tool for understanding honeybee population declines, and comes as the USDA is curtailing other research programs. It’s also another step toward undoing President Barack Obama’s government-wide focus on protecting pollinators, including bees and butterflies, whose populations have plummeted in recent years.

Orangutans: Palm oil industry still threatens the lives and habitat of ‘people of the forest’

Orangutans: Palm oil industry still threatens the lives and habitat of ‘people of the forest’

The New York Times reports: The men came at Hope and her baby with spears and guns. But she would not leave. There was no place for her to go. When the air-gun pellets pierced Hope’s eyes, blinding her, she felt her way up the tree trunks, auburn-furred fingers searching out tropical fruit for sustenance. By the end, Hope’s torso was slashed with deep lacerations. Multiple bones were broken. Seventy-four pellets were lodged in her body. Her months-old baby had…

The search for extraterrestrial technology finds none

The search for extraterrestrial technology finds none

The Guardian reports: The close encounter will have to wait. Astronomers have come up empty-handed after scanning the heavens for signs of intelligent life in the most extensive search ever performed. Researchers used ground-based telescopes to eavesdrop on 1,327 stars within 160 light years of Earth. During three years of observations they found no evidence of signals that could plausibly come from an alien civilisation. The only signals picked up by the Green Bank telescope in West Virginia and the…

We are more rational than we are told

We are more rational than we are told

Steven Poole writes: Humanity’s achievements and its self-perception are today at curious odds. We can put autonomous robots on Mars and genetically engineer malarial mosquitoes to be sterile, yet the news from popular psychology, neuroscience, economics and other fields is that we are not as rational as we like to assume. We are prey to a dismaying variety of hard-wired errors. We prefer winning to being right. At best, so the story goes, our faculty of reason is at constant…

‘Hell on Earth’ scenario predicted if climate crisis doesn’t trigger immediate drastic action

‘Hell on Earth’ scenario predicted if climate crisis doesn’t trigger immediate drastic action

Al Jazeera reports: A climate change paper grabbed headlines this week with its terrifying prediction of what the world will be in 30 years’ time – absent drastic and immediate change to human societies. “World of outright chaos,” “Climate apocalypse,” “We’re all gonna die,” the media banners blared. The sobering headlines and equally disconcerting stories beneath described a “scenario analysis” by an Australian think-tank, Breakthrough National Center for Climate Restoration. The paper portrayed what the year 2050 will look like…

People eat at least 50,000 plastic particles a year, study finds

People eat at least 50,000 plastic particles a year, study finds

The Guardian reports: The average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity, according to the first study to estimate human ingestion of plastic pollution. The true number is likely to be many times higher, as only a small number of foods and drinks have been analysed for plastic contamination. The scientists reported that drinking a lot of bottled water drastically increased the particles consumed. The health impacts of ingesting microplastic are…

Influential panel votes to recognize Earth’s new epoch: The Anthropocene

Influential panel votes to recognize Earth’s new epoch: The Anthropocene

Nature reports: A panel of scientists voted this week to designate a new geologic epoch — the Anthropocene — to mark the profound ways in which humans have altered the planet. That decision, by the 34-member Anthropocene Working Group (AWG), marks an important step towards formally defining a new slice of the geologic record — an idea that has generated intense debate within the scientific community over the past few years. The panel plans to submit a formal proposal for…

Living on Mars is a misguided fantasy

Living on Mars is a misguided fantasy

Philip Ball writes: Who said this? “I’ve been having to say everywhere I go that there is no planet B, there is no escape hatch, there is no second Earth; this is the only planet we have.” If you’re a science fiction fan the answer might surprise you: it was the writer Kim Stanley Robinson, whose Mars trilogy is an ultimately utopian series of tales that describe the terraforming of Mars – planetary engineering to give it an Earth-like environment…

Humans are killing off most large wild animals as sixth mass extinction advances

Humans are killing off most large wild animals as sixth mass extinction advances

The Guardian reports: Humanity’s ongoing destruction of wildlife will lead to a shrinking of nature, with the average body size of animals falling by a quarter, a study predicts. The researchers estimate that more than 1,000 larger species of mammals and birds will go extinct in the next century, from rhinos to eagles. They say this could lead to the collapse of ecosystems that humans rely on for food and clean water. Humans have wiped out most large creatures from…

Loss of biodiversity is just as catastrophic as climate change

Loss of biodiversity is just as catastrophic as climate change

Robert Watson writes: A colleague recently described how fish would swim into her clothing when she was a child bathing in the ocean off the coast of Vietnam, but today the fish are gone and her children find the story far-fetched. Another recalled his experiences just last year in Cape Town – one of the world’s most attractive tourism and leisure destinations – when more than 2 million people faced the nightmare prospect of all taps, in every home and…
